Virtual ASPI driver
The ASPI support currently embedded within OS/2 2.1 allows any OS/2 application to send commands to a SCSI device. However there are a large number of DOS and Windows applications that are could be supported if there commands were routed to OS2ASPI.DMD.
VASPI.SYS is a virtual device driver that will allow DOS applications to issue SCSI commands that will be handled by OS2ASPI.DMD. If you have an existing DOS ASPI application it should now be able to run in a virtual DOS session under OS/2 2.1.
